If the recent spate of bedroom buddy romantic-comedies were the sisters of the Brady Bunch, "Friends with Benefits" would be Marcia, "No Strings Attached" would be Jan, and "What's Your Number?" is little Cindy Brady. Neither as grating and obnoxious as Jan, but not quite as shiny and earnest as Marcia, "What's Your Number?" works hard to differentiate itself from the pack, has a few truly winning traits, but ultimately will always be lumped into the bigger kitschy bunch she's associated with.

"What's Your Number?" stars Anna Faris as a woman unwilling to go over twenty sexual partners once she learns that she's risking more than being labeled a slut. In fact, research proves it will diminish her chances of finding a husband to a paltry 4% (side note: we'd love to see the oh-so scientific study this premise, which the filmmakers claim is real, was based on). To find her husband, she goes green and decides to do some sexual recycling, revisiting all of her old flames, hoping one of them might be her true love. Luckily she's assisted in her quest by her diabolically hot neighbor played by Chris Evans. Gee, anyone wonder if he'll be lucky number twenty-one?

Romantic comedies follow a formula we all know like the back of our hand. The question is, are the people you're watching and the situations they find themselves in compelling enough to make the journey interesting and worthwhile? "What's Your Number?," though unoriginal and, at times tiresome, is better than one might expect and has some moments of genuine delight, most thanks to an oft semi-nude Evans who has palpable chemistry with everything he shares the screen with, whether it's a sandwich, a guitar or Anna Faris. Speaking of, Faris is no Mila Kunis ("Mila, Mila, Mila!"), and her brand of slap sticky humor can run thin, but when she relaxes into the role and stops pushing for laughs, she can be winning.

If watching two pretty people slowly work themselves together like romantic Legos floats your boat, seeing Faris and Evans march toward the inevitable is perfectly enjoyable. Unfortunately, it's also kind of forgettable, much like the youngest child of six.
